VEHICLE-WHEEL.

Specification of Letters Patent. Patented Allg. 29, 1911- Application led February 4, 1911. Serial No. 606,596. Y

To all whom it may concern: A

Beitknown that I, CHARLES UL'MER, a citizen of the United States, residing at Lisbon, in the county of Ransom and State ot North Dakota, have invented a new and useful Vehicle-Wheeh of Which the following is a specification. It is the object of the present invention to provide an improved vehicle Wheel of that type embodying a pneumatic cushioning element which is arranged between' normally concentric members constituting the hub of the wheel.

It is one aim of the present invention to provide, in a wheel ofrthis type, novel means for holding the'outer. one of the two members mentioned, for rotation with the inner one thereof, the means being so constructed that it may be readily manipulated to separate the two sections.

In the' accompanying drawings :--Figure 1 is a view in side elevation parts being broken away, of a Wheel constructed in accordance with the present invention. Fig. 2

is a vertical sectional view therethrough.

Fig. 3 is a perspective View of one ofthe hub plates.

In the drawings the hub of the wheel is illustrated as including, in its structure, a Y member 5 having lateral threaded extensions `(3. The member is fitted upon an axle 7 or designed toibc so fitted and in its periphery` is formed with a circumscrlbmg groove 8.

which forms one of two seats for a pneu- Hub plates 1() and 1l, are

threaded on to the extensions (5 ot the meinher 5 1n the manner 1lluslrated in Fig. 2 of' ymatie cushion 9.

the drawings and the plate 10 is formed with 4 a threaded sleeve extension 12 on to wluch is threaded a cap nut 155. '.fhe other huh plate, ll, is formed with a squared head lll:v

a groove 17 which opposes the groove 8 and forms the other seatV for the cushion 9, it being understoodl that this cushion serves as a yieldable means for spacing the annulus from the-hub. The annulus is formed `With laterally projecting annular flanges 18 which are threaded as at 19 and are formed at intervals with slots 20. The arms l5 of the hub plates 10 and 1l project into the slots 20 and are confinedtlierein, for limited vention itwill be readily understood that Whereas the parts of the wheel are normally held firmly in assembled relation and against accidental disarrangement, it being noted that the arms 15 are secured by means of bolts 24 to the sides of the hub 5, by removing these bolts, removing the rings'2l, and then removing the hub plates, the part-sof vthe wheel `may be readily disassembled.

\V hat is claimed is n InA a vehicle wheel, a hub having a circumscribing groove, an annulus formed in its inner side with a groove, a pneumatic cushion arranged'bctween the hub and annulus and fitting in the groove, the annulus having lateral threaded llanges, the flanges being formed with radial slots, the hub being formed with lateral threaded extensions, hub plates threaded upon the extensions and having radiating arms working in the slots in the annulus, the arms being secured removably to the hub radially beyond the extensions thcreo't, clamping rings threaded upon the flanges, one to cach flange aud confining the arms in the ysaid slots, spokes radiating from the annulus, and a riin supported at the outer ends ot' the spokes.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of twowitnesses.
